Abstract
Description
Die Erfindung betrifft einen Formkörper aus biologisch abbaubarem Material nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zu dessen Herstellung nach Anspruch 2.The The invention relates to a shaped body of biodegradable material according to the preamble of the claim 1 and a method for its production according to claim 2.
Der Formkörper ist für den Einsatz im Möbelbau, der Verpackungs- und Automobilindustrie oder im Wohnungsinnenausbau geeignet. Insbesondere lässt sich der Formkörper in Form von Platten oder dreidimensional geformten Halbzeugen bzw. Fertigteilen im Möbelbau- und Innenausbau, als Beplankungsmaterial für Innen- und Außenwände, Fußböden und Decken oder in vergleichbaren Bereichen einsetzen.Of the moldings is for use in furniture construction, the packaging and automotive industry or in housing interiors suitable. In particular, lets itself the shaped body in the form of plates or three-dimensionally shaped semi-finished products or Prefabricated parts in furniture and interior fittings, as a planking material for interior and exterior walls, floors and Use blankets or comparable areas.

Die bisher verwendeten Zerkleinerungsverfahren in Verbindung mit Seegras beruhen im Wesentlichen auf der Kürzung der bis zu 1m lagen Blätter. Der grundlegende Nachteil hierbei besteht darin, dass die Mikrofaserstruktur des Rohstoffes unberücksichtigt bleibt und nicht für die Herstellung von Werkstoffen mit homogener Struktur genutzt wird. In den genannten Schriften werden hohe Anteile an Bindemittel bzw. Zuschlagstoffen eingesetzt, um die erforderlichen Festigkeiten zu realisieren. Eine Herstellung von dünnwandigen, hochfesten dreidimensional geformten Produkten aus Seegras ist nach den genannten Verfahren nicht möglich.The Previously used comminution methods in connection with seaweed are based essentially on the reduction of leaves up to 1m. Of the fundamental disadvantage here is that the microfiber structure of the raw material is disregarded stays and not for the production of materials with homogeneous structure is used. In the cited documents, high levels of binder or Aggregates used to provide the required strength realize. A production of thin-walled, high-strength three-dimensionally shaped Seaweed products are not possible according to the procedures mentioned.
Die Aufgabe der Erfindung besteht darin, Seegras einer weiteren nutzbringenden Anwendung zuzuführen.The The object of the invention is seaweed another beneficial Apply application.
Erfindungsgemäß wird die Aufgabe durch einen Formkörper mit den im Anspruch 1 genannten Merkmalen gelöst.According to the invention Task by a molding solved with the features mentioned in claim 1.
Die Erfindung wird weiterhin durch ein Verfahren zur Herstellung des Formkörpers mit den im Anspruch 2 genannten Merkmalen gelöst. Vorteilhafte Varianten des Verfahrens sind Gegenstand von Unteransprüchen. The Invention is further characterized by a method for producing the molding solved with the features mentioned in claim 2. Advantageous variants of the method are the subject of subclaims.
In dem der Erfindung zugrundeliegenden Verfahren werden die Fasern im Seegras einem mechanischen oder thermomechanischem Aufschluss und Mahlprozess unterzogen, bei dem auch eine Freilegung von Fibrillen erfolgt. Der Aufschluss des Seegrases kann bei unterschiedlichen Feuchtegehalten in Scheibenmühlen oder im Extruder erfolgen. Die fibrillierten Fasern werden mit natürlichen oder synthetischen Bindemitteln mit Anteilen zwischen 3 bis 15 % besprüht, zu Faserfliesen gestreut und in einem Heißpressprozess unter Einwirkung von Druck und Temperatur zu Platten oder Formkörpern mit einer Dichte im Bereich von 400 bis 1200 kg/m3 verpresst. Formteile können durch unterschiedliche Pressgesenke oder im Extruder erzeugt werden.In the process on which the invention is based, the fibers in the seagrass are subjected to a mechanical or thermomechanical digestion and milling process, in which an exposure of fibrils is also carried out. The digestion of the seaweed can take place at different moisture contents in disk mills or in the extruder. The fibrillated fibers are sprayed with natural or synthetic binders in proportions between 3 to 15%, spread to fiber tiles and pressed in a hot pressing process under pressure and temperature to plates or moldings having a density in the range of 400 to 1200 kg / m 3 . Moldings can be produced by different pressing dies or in the extruder.
Durch die verbesserte mechanische Verankerungen der fibrillierten Fasern werden verbesserte Werkstoffeigenschaften bei geringen Bindemittelanteilen erreicht. Aufgrund des hohen natürlichen Salzgehaltes von Seegras besitzen die Werkstoffe aus diesem Material jedoch eine verbesserte Brandfestigkeit.By the improved mechanical anchoring of the fibrillated fibers be improved material properties at low binder levels reached. Due to the high natural Salinity of seaweed own the materials of this material however, an improved fire resistance.
